Osprey is a peer-to-peer enabled content distribution system. A metadata management system for software and document collections enables local and distributed searching of materials. Items are available for download directly via URL or indirectly via the BitTorrent peer-to-peer protocol. Two components exist: the Osprey web application and permaseed (permanent seed). The web application includes metadata management for finding and exploring available content, as well as a BitTorrent tracker. The latter is a BitTorrent server application, which links content on a server to a BitTorrent swarm. Permaseed addresses the typical transience of BitTorrent file distribution by providing a daemonized service that functions more like a server than a BitTorrent client.
